RILLEOARD AND PROCESS FOR REMOVING vros'rERs ERoii/ r` yisiLLEoAaDs.l

To all whom t may con-cem: v y V Be it known that 1,' CLARENGE A. BEALL, a citizen of the United States, residing at Saticoy,-in the county of AVentura andState of California, have invented anew and use ful. Billboard and Process for Removing Posters from Billboards, of which the fol lowing is a specification.

rlhis invention relates to method andap-l paratus for removing paper, ibreor other material from bill boardsy or .walls which paper, fibre or other vmaterial has `been se-v 'cured to the bill, `board orjwall by adhesive paste,y mucilage or like material.

At the present time Abill posting companies are put to a large expense in order to remove old posters from bill boards or the like as by the bill boards and methods of removing bills from the same now in use the old posters must be removed by tearing, scrapingk and washing from the outside of the posters before a new poster may be applied. This requires a considerable time and largevex-y pense for labor,.the old paper being removed in scraps making a dirty operation and requiring additional time for'cleaning up the old paperv from around thev bill board. Y

It is an object of the present invention to provide a method and` apparatus by which old posters` or the like may be removed from bill boards with a less expenditure of labor and by which the old posters may be removed in large pieces or in toto therefrom tothe end thatthe expense and loss'of time of the present tearing and scraping methods vention will best be understood from a de` scription of the preferred example of a method and apparatus embodying the invention,

for which purpose reference is made to the accompanying drawings in which a preferred form or example of an apparatus einbodying the invention is disclosed and byY which apparatus a preferred method of re- Appiication inea Mami; 16,1925. serial No. 15,914.

moving o ldY posters or the lili/e may be carriedvout.

yIn the drawings:

board or apparatus for removing posters` therefrom embodying theinvention.v

Fig. 2 is a fragmentary elevation atrighta bill board preferably secured to a wooden` backing 3 and surrounded by a frame et. In

Aorder that the present method oflremovingy posters from the bill board could be carried out and that such ordinary bill board may be converted to anapparatus embodying the present invention there is'placed in front of such plate 2 a perforated plateY 5 preferably of similar ydimensionsto that of the plate 2 and having a large number of equally spaced vperforations 6. Theperforated plate 5 is preferably held slightly in front of the normal plate 2 of the billboard by suitable means such as spacers 7 to form therebetween a chamber 8 for distribution of an adhesive disintegrating agent; There is also connected to the chamber 8 a number of Figure 1 is a front elevation of a bill l small chests 9 at the rear ofthebill board, l

all of which are preferably connected togethler by pipes l() so that they may be supplied f bill board from a common pointu In use the posters ll are secured to `the front surface ofthe perforated plate 6 by paste or mucilage or any other preferred flier it is desired to re-` form of material. move the same to place a. new poster upon the board such posters l1 may then be removed without requiring the usual tearing and scraping through introducing an agent adapted to disintegrate the adhesive holding the poster 11 to thevplate 5, this agent being passedk through pipes lO and chest 9 and distributed throughout the chamber k8 so that it may pass through vthe perforations 6 of the perforated plate 5 and effectively disintegrate the adhesive holding the poster ll to said plate 5. With ordinary paste or mucilage wet steam or hot` water is preferably employed. The wet steam may be supplied from any portable steam boiler. Then introduced into the chamber 8 it will vsoak the adhesive holding the poster 11 to the per.

orated Yplate fandthe-oldposter may then be readily removed in large-pieces. K

In Figure 3 there is shown a modilied form of thefapparatuscin which the perforated plate 5a is held by the rear plate 2 by lugs 7 turned in romthe rperforlztted 'plate 5 in forming its perforations 6a.

-lVliile .the method and apparatus forren'ioving posters from bill boards herein-described is Well adapted to l'carry out the objects-otl Atheinvention, various modifications ymay be made 'Without departing from the 4principles of the invention and the inplate, means forming a chamber rearwardly of the plate, and -means for introducing an `agent into said chamber adapted to disintegrate the adhesiveA employed to retain the yposterto''said*perforated plate.

2. An apparatus of the class described, comprising a front and rear plate spaced apart to provide aA chamber therebetween the front plate being perforated and adapted to operate to hold the poster thereto by the aid of an adhesive', and means orfsupplying to "said cli-amber an agent for disintegrating said adhesive.

3. A billboard of the cla-ss described coinprising a perforated plate, aposter secured by 'adhesive to one side oi-l such perforated plate, and means 4for supplying to the other side of said perfor-ated plate an adhesive disintegrating material. p Signed at Los `Angeles Calif. this 9 day o l\l-a1*c'h,'1l92`5.
